Abstract

Aim: Dimedone , gamma pyrone and barbituric acid and their derivatives have also been found to be very important from their application point of view. Thus our aim was to prepare more derivatives from them. Method : Dimedone , gamma pyrone and barbituric acid have been treated with dimethyl sulphoxide and acetic anhydride reagent under varying temperature conditions in order to get more compounds. Result: The interaction of DMSO-Acetic anhydride with Dimedone (1) gives (2) and (3), with gamma pyrone (5) gives (6) ,(7), and with barbituric acid (10) gives (11 ) and (12). Conclusion: A number of compounds were synthesized .
